RlGHT AND LEFT OPENING DOOR.

SPECIFICATION forming part of Letters Patent No. 707,910, dated August 26, 1902.

Application filed August 4, 1899. Serial No. 726,187. (No model.)

.To a. whom it may concern:

Be it known that we, FERDINAND FISCHER and LUDWIG KIEFER, citizens of theEmpire of Germany, residing at Carlsruhe, Germany, have invented certain new and useful Improvements in Right and Left OpeningDoors, of which the following is a specification.

This invention relates to a right and left opening door adapt-ed particularly to railroad cars or coaches. In this door a lug c011- nected with its respective hinge bar and which lug prevents the door from being lifted out of place swings through a lateral cut in the corresponding hinge-knuckle at the opening edge of the door, while the door at the other or hinge edge is supported on the hingeknuckle and secured against lifting by the under engagement of the lug at such hinge edge. The hinge knuckles are secured or fixed to the jamb, and the door, or ratherits opening edge, remains free from these parts tending to obstruct or endanger traffic or passage.

This invention is set forth in the following specification and claims and illustrated in the annexed drawings, in which Figure 1 is a face view, partly in section, of a door with the arrangement preventing such door lifting out of place or being dismounted. Fig. 2 is a horizontal section alongcc 00, Fig. 1. Fig. 3 shows an edge of the door locking in the direction of the arrow p, Fig. 1. Fig. 4: is a side elevation along the section-line 3 y looking in the direction of the arrow 19, Fig. 1. Fig. 5 is a perspective view of the parts for preventing the door lifting out of place, the parts being separated and shown on a larger scale than in the preceding figures. Fig. 6 is a perspective view like Fig. 5, showing said parts assembled.

The door A, Fig. l, is shown at each edge with a knob or handle I) and 0, respectively, adapted to lift or free its corresponding latch b or c. A link or bar F tends to depress or engage one latch or-locking-lever as the other one is lifted or disengaged. At the edge or hinge portions D of the door are sliding rods G and H. As one latch or the other, bor c, is lifted it lifts its corresponding rod G or H. These rods carry or are connected to the hinge-pins g, as seen more in detail in the illustration of the hinge-rod G in Fig. 5. As

1 edge of the door.

a rodG or H is lifted the corresponding hingeknuckle D at that edge of the door. This edge thus becomes free to open or close in contradistinction to the opposite edge of the door, which may be distinguished as the hinge The sockets or knuckles D are secured to the jambs or opposite sides of the passage closed by such door. One of the hinge parts at each side of the door-for example, the central hinge parthas at each hinge-rod G or H, together with pin g, a hooklike projection or nose 9, which when the door is closed lies directly under the hinge-knuckle D. (See right hand of Fig. 1.) On lifting the slide-rod at one edge of the door the lugg rises freely alongavertical slot 6, Figs. 4, 5, and 6,0f the knuckle D, and upon the door or that edge of the door then opening said lug g moves freely through the lateral cut or passage 6 out of the stationary knuckle D. In Fig. 5 are shown a hinge-pin and lug and the corresponding knuckle D, secured to the corresponding jamb, as also a piece of the sliderod G separate from the door. On the opposite side or edge of the door the other sliderod H, Figs. 1 and 2, by said known arrangement of cross-link F between latches b c is held in lowered or depressed position, so that the door at this edge remains engaged to the hinge-knuckles. Atthe same time the lugs at this hinge edge as soon as the door opens or swings moveunder the uncut or broken part of their hinge-knuckles, Fig. 6, so that this hinge edge is prevented from lifting out of place. Manifestly the securing device could also be applied to the upper or lower hinge or to several hinges.

To insure automatic return or descent of the slide-rods G H and hinge-pins g, springs J and K can be suitably applied. Returnsprings can also be applied to the latches b c, if desired.

Having fully described our invention, what we claim, and desire to secure by Letters'latcut, is-- 1. The combination with the door and its frame provided with sockets, having an L- shaped opening, of bell-crank latches pivotally connected to said door, springs carried by the door and bearing against one arm of each of the bell-crank latches for normally ICO retaining them in a latching position, vertically-adjustable rods arranged in the doorframe and operated by the said latches when the latter are operated, pins forming pivots carried by the rods and adapted to engage in the said sockets when the door is opened in one direction or the other, and hook-like pro jections carried by the rods and adapted to be passed through the L-shaped openings when the rods and door are operated.

2. The combination with the door and its frame provided with sockets, provided with a vertically and laterally extending opening, of bell-crank latches pivotally connected to said door, springs carried by the door and bearing against one arm of each of the bell-crank latches fornormally retaining them in a latching position, vertically-adjustable rods arranged in the door-frame and operated by the said latches when the latter are operated, pins forming pivots carried by the rods and adapted to engage in the said sockets when the door is opened in one direction or the other, and means carried by the rods and adapted to operate in the said openings to permit of the disengagement of the acting pivots during the opening or closing of the door.

3. The combination with the door and its frame provided with sockets, provided with L-shaped openings, of bell-crank latches pivotally connected to said door, springs carried by the door and bearing against one arm of each of the bell-crank latches for normally retaining them in a latching position, verti cally-adjustable rods arranged in the doorframe and operated by the said latches when the latter are operated, pins forming pivots carried by the rods and adapted to engage in the said sockets when the door is opened in one direction or the other, hook-like projections carried by the rods and adapted to operate in said opening to permit the disengage ment of the acting pivots during the opening or closing of the door, a rod pivotally connected to one end of one arm of one of the bell crank latches and adapted to bear against one arm of the other of the said bell-crank latches to prevent the simultaneous operation of the said latches, and means for operating said latches.

4. The combination with the door and its frame provided with sockets, of bell-crank latches pivotally connected to said door, springs carried by the door and bearing against one arm of each of the bell-crank latches for normally retaining them in alatching position, vertically-adjustable rods arranged in the door-frame and operated by the said latches when the latter are operated, lugs forming pivots carried by the rods and adapted to engage in the said sockets when the door is opened in one direction or the other, means carried by the rods and adapted to permit the disengagement of the acting pivots during the opening or closing of the door, a rod pivotally connected to one end of one arm of one of the bell-crank latches and adapted to bear against one arm of the other of the said bell-crank latches to permit the simultaneous operation of the said latches, means for operating said latches, and means carried by the rods to permit of closing the door independently of the operating means for the latches.

5. A right and left opening door having slide-rods G and H, hinge-pins and lugs carried by the rods, and hinge-knuckles having longitudinal and lateral cuts, said pins when lifted by the rods clearing the knuckles and said lugs when lifted passing through the longitudinal to the lateral or clearing out so as to leave the adjacent edge of the door free to open,andsaid lugs when the hinge-pins are not lifted being made to swing or move under the knuckles to prevent the adjacent edge of the door lifting out of place.
